C Contains a list of vertices. When a particle decays, is absorbed
24
C or converts to e+e- a new vertex is created. Various pointers
25
C relate the vertex list to the full particle list in QQTRAK.INC.
27
C VPROD(IT) is the vertex at which particle IT was produced while
28
C IVDECA(IT) is the vertex at which particle IT either decayed, was
29
C absorbed or converted, or 0 if nothing happened. Conversely,
30
C ITRKIN(IV) is the incoming track to vertex IV or 0 if IV = 1 (the
31
C production vertex has no incoming track). ITRKOU(IV) is the first
32
C outgoing track from vertex IV or 0 if the track is absorbed.
